TYPE- lFOLLOWER FOR TYPE-=CONTAlNlNG CHANNELS.

SPECIFICATION forming part of Letters Patent No. 642,335, dated January 30, 1900. Application filed December 3,1897. Serial No. 660,590. (No model.)

To all whom it may concern.-

Be it known that I, LOUIS KOSSUTH J OHN- SON, a citizen of the United States, residing in the city of New York, (Brooklyn,) in the county of Kings and State of New York, have invented certain new and useful Improvements in TypeFollowers for Type-Containing Channels, of which the following is a specification suflicient to enable others skilled in the artto which the invention appertains to make and use the same.

My invention relates to slugs or type-followers used to confine and support types in containing-channels and is designed to render the follower convertible into a locking device when desired to secure the types for storage, transportation, the.

The invention consists, essentially in forming the follower with expanding side walls tending constantly to press against the internal side walls of a containing-channel and increase the frictional contact therewith, in conjunction with means for clamping said expanding side walls together, so that the device may be used in the same manner as a loose type-follower of ordinary construction.

In carrying out my invention I do not confine myself to the identical form and construction of parts shown, as various mechanical expedients and equivalents may be resorted to without departing from the spirit and intent of my invention.

In the accompanying drawings, Figures 1 and 2 are elevations of opposite sides of the follower. Fig. 3 is an end elevation of the follower clamped; Fig. 4, an end elevation of the follower expanded; Fig. 5, asection upon plane of line 5 5, Fig. 1; Fig. 6, a side elevation of the follower with clamp loosened; Figs. 7 and 8, respectively front and rear views of the follower closed; Fig. 9, a front view of the follower expanded; Fig. 10, an elevation showing the follower closed and in the type-containing channel; Fig. 11, a similar view showing the follower expanded.

The side walls A A are hinged together or pivotally connected in any suitable manner, as by the pintle 12, (shown in Fig. 5,) and their front ends tend constantly to expand or separate by reason of a spring 3 interposed On one side wall is pivoted a bifurcated clamp-lever O, recessed to re ceive the bearing a, so as to render the side of the lever flush with the side walls A A of the follower when closed. The exterior side walls A A are also recessed, as at a (L to receive the bifurcations c c of the clamp-lever c.

The application and use of the device are simple and obvious. hen it is desired to use it as an ordinary loose slug or follower, the front ends of the side walls A A are pressed toward each other against the resistance of the spring 3, and the bifurcations c c of the clamp-lever O are pressed into the recesses CL a and then hold the side walls A A closed against the resistance of the spring .9, in which condition the device is adapted to perform any of the functions of an ordinary channel-slug or type-follower.

When it is desired to use the device as a lock to secure and maintain the types within the channel, it is simply necessary to press 011 the rear end 0 of the clamp-lever O, thereby releasing the bifurcations c c from the recesses a a and allowing the spring to expand the front edges of the side walls forcibly against the interior side walls of the channel, as illustrated in Fig. 11.

By thus adapting a single device to perform the double function of a type-follower and a locking-slug I equip each channel permanently and avoid the danger of loss or displacement incident to the use and substitution of separate devices, at the same time contributing to the convenience of the user.

hat I claim as my invention, and desire to secure by Letters Patent, is-

1. A combined slug and type-follower for type-containing channels consisting of two side pieces pivotally connected, with an expanding-spring interposed between them and a bifurcated clamping-lever fulcrumed to one side piece substantially in the manner and for the purpose described.

2. In a combined locking-slug and type-follower, for type-containing channels, the combination of the pivotally-connected side pieces A A, the expanding-spring s, and the bifurcated catch-lever O, the whole constructed and operating substantially in the manner and for the purpose described.

3. In a combined locking-slug and type-follower for type-containing channels the comand operating substantially in the manner 'bination of the pivotally-connected sigle pieces and for the purpose described.
